In the early part of the story, Tohru briefly moves back in with her grandfather, who is now sharing his apartment with Tohru's paternal aunt and her kids. Her aunt's family makes it clear they see Tohru as something of a burden, until the aunt reveals she hired a private detective to do some checking on Tohru and knows she was staying with the Sohmas. The aunt's reasoning was that her son wants to be a police detective when he's older, and "Having a relative with a criminal record would jeopardize that." The aunt remembered what Kyoko was like when she was Tohru's age, figured "like mother, like daughter", and orders her not to do anything so "reckless" in the future if she wants to keep living with them. Her cousins pretty much call her a whore, and Tohru stands there, silently taking it, until her grandpa slaps the male cousin. The anime makes this better by removing the Cloud Cuckoo Lander aspect of Tohru's grandfather.
Grandpa: Tohru, I apologize. Please don't think too harshly of them. They're just disagreeable folks by nature.
